Definitions
- This invention relates to electrical jacks of the type adapted for side-by-side mounting in electrical cross-connect jack panels found in telephone and other telecommunication exchanges.
- the prior art electrical jack unit is identified with the numeral 10 having an integral cast frame 12 with a sleeve section 14 and a support beam section 15.
- the support beam section 15 includes a single support beam 16 that extends outward at a right angle to the sleeve section 14.
- the sleeve section 14 includes an output monitor sleeve member 18, an output sleeve member 20 and an input sleeve member 22 that extend outward from a forward surface of the sleeve section for receiving cylindrical jack plugs.
- the sleeve section 14 has mounting holes 24 at the ends thereof for mounting the electrical jack unit in parallel side-by-side relationship with other jack units in an electrical jack panel.
- the prior art electrical jack unit 10 includes three jack spring switch assemblies that are identified as a monitor output jack spring switch assembly 26, an output jack spring switch assembly 28 and an input jack spring switch assembly 30.
- Each of the switch assemblies 26, 27 and 30 correspond with respective sleeve members 18, 20 and 22.
- the switch assemblies 26, 28 and 30 are secured to the support beam 16 by bolts 32 that extend through the switch assemblies and the support beam 16.
- the electrical jack unit 10 illustrated in FIG. 1 was a substantial improvement in the technology, it still possessed significant weaknesses.
- the cast frame 12 is quite rigid it does permit the spring assemblies 26, 28 and 30 to twist with respect to the support beam 16 in a lateral direction enabling the switch contacts to engage adjacent switch contacts of adjacent units, causing electrical shorting.
- the insertion of cylindrical jack plugs into their respective sleeve members 18, 20 and 22 caused substantial moment forces to be produced with respect to the bolts 32 minimizing the pressure that can be applied to the physical switch contacts.
- the switch assemblies become loose and are rendered ineffective.
- One of the principal objects of this invention is to provide a much improved electrical jack unit that overcomes many of the disadvantages of the prior art electrical jack units, particularly with respect to the electrical jack unit 10 illustrated in FIG. 1.
- the advantages of this invention will become apparent upon reading the following detailed description of a preferred embodiment.

- FIG. 13 is a isolated isometric view of a cast frame structure of the electrical jack unit illustrated in FIG. 10.
- FIG. 2 illustrates an electrical jack unit generally designated with the numeral 40 that incorporates the preferred embodiment of this invention.
- the electrical jack unit 40 has a cast frame structure 42 made of a nonferrous, electrically conductive material.
- the cast frame structure 42 includes a sleeve section 44 that has a front face 45A and a rear face 45B.
- the cast frame structure 42 further includes a beam section 46 that is formed integrally with the sleeve section 44 and extends outward cantilevered from the rear face 45B substantially perpendicular to the sleeve section 44.
- the sleeve section 44 has upper and lower outer mounting ends 48 with holes 50 formed therein for enabling the electrical jack unit 40 to be mounted to an electrical jack panel adjacent to other electrical jack units that provides access to telecommunication circuits that are connected to the electrical jack panel.
- Sleeve section 44 includes an output monitor sleeve member 52 that is spaced from an output sleeve member 54 which is in turn spaced from an input sleeve member 56.
- Each of the sleeve members 52, 54 and 56 extend outward from the front face 45 perpendicular to the elongated direction of the sleeve section 44.
- Each of the sleeve members 52, 54 and 56 include a cylindrical bore 58 formed therein passing through the front surface 45A to the rear surface 45B.
- the cylindrical bore 58 is designed to receive a cylindrical jack plug, that is not illustrated, for making frictional electrical contact with spring contact switches.
- the beam section 46 includes a support beam 60 that extends outward cantilevered from the rear surface 45B in a substantially perpendicular orientation to the sleeve section 44.
- the support beam 60 extends outward intermediate the output monitor sleeve member 52 and the output sleeve member 54.
- the support beam 60 includes mounting holes 62 (FIG. 5) that extend therethrough in a vertical direction substantially parallel with the sleeve section 44.
- the beam section 46 further includes a support beam 64 that extends outward cantilevered from the sleeve section 44 parallel but spaced from the support beam 60 intermediate the output sleeve member 54 and the input sleeve member 56.
- the support beam has holes 66 formed vertically therethrough that are vertically aligned with the holes 62.
- the support beam 64 is spaced from the support beam 60 a sufficient distance forming an open-ended U-shaped cavity 68.
- the electrical jack unit 40 includes three jack spring switch asemblies 70, 72 and 74.
- the monitor output jack spring switch assembly 70 is mounted on top of the support beam 60 in alignment with the output monitor sleeve member 52.
- the output jack spring switch assembly 72 is mounted in the cavity 68 to the bottom side of support beam 60 and to the top side of the support beam 64.
- the input jack spring switch assembly 74 is mounted to the underside of the support beam 64 in alignment with the input sleeve member 56.
- Each of the switch assemblies 70, 72 and 74 include electrically conductive spring blades 76 that are spaced by insulation spacers 78. The contacts of the spring blades 76 are movable perpendicularly to the support beams 60, 64.
- the switch assemblies 70, 72 and 74 are securely mounted to the support beams 60 and 64 by bolts 80 that extend vertically through the switch assembly 70, 72 and 74 and through the mounting holes 62 and 66 in the support beams 60 and 64.
- the two support beams 60 and 64, in conjunction with the bolts 80 securely mount the switch assemblies 70, 72 and 74 in a very rigid manner to prevent any lateral twisting.
- the support beams 60 and 64 minimize the creation of moment forces that may be created on the spring assemblies when a cylindrical jack plug is inserted into one of the sleeve members 52, 54 or 56. Consequently the electrical jack unit 40 has a considerably longer life and is considerably less likely to become loose or to become ineffective after considerable use.
- support beams 60 and 64 provide greater rigidity enabling use of increased spring contact pressure between the blades 76 and the jack plug to provide more consistent electrical contact. Furthermore, the support beams 60 and 64 provide isolation RF shielding between the switch assemblies 70, 72 and 74 to minimize frequency interference. Particularly support beam 60 provides RF shielding for a monitor signal that is carried by the switch assembly 70. This feature is particularly important for high frequency communication transmission.
- support beams 60 and 64 provide for a more vertical parallel stack of switches enabling the electrical jack units 40 to be mounted adjacent other electrical jack units in an electrical jack panel with less tendency for electrical shorting between adjacent electrical jack units. Such a feature also minimizes the number of units that need to be "reworked” because of twisting or misalignment of the switch assemblies.
- the electrical jack unit illustrated in FIG. 6 is identified generally with the numeral 82.
- the unit 82 has a cast frame structure with a sleeve section 86 and a beam section 88.
- Sleeve section 86 includes an output monitor sleeve member 90, an output sleeve member 92, an input sleeve member 94 and input monitor sleeve member 96.
- the beam section 88 includes three spaced support beams.
- the support beam 98 extends outward from the rear surface intermediate the output monitor sleeve 90 and the output sleeve 92.
- the second support beam 100 extends outward from sleeve section 86 intermediate the output sleeve member 92 and the input sleeve member 94 forming a cavity 102 between the support beams 98 and 100.
- the third support beam 104 extends outward perpendicular to the sleeve section 86 intermediate the input sleeve 94 and the input monitoring sleeve member 96 forming a cavity 106 intermediate the support beams 100 and 104.
- the electrical jack unit 82 has four jack spring switch assemblies. Specifically the unit 82 includes an output monitor jack spring switch assembly 108 that is aligned with the output monitor sleeve 90 and is mounted to the top surface of support beam 98. An output jack spring switch assembly 110 is mounted in the cavity 102 between the support beams 98 and 100 in alignment with the output sleeve 92. An input jack spring switch assembly 112 is mounted in the cavity 106 between support beam 100 and support beam 104 in alignment with the input sleeve 94. An input monitor jack spring switch assembly 114 is mounted beneath the support beam 104 in alignment with the input monitor sleeve member 96. Bolts 116 extend through the switch assemblies 108, 110, 112, and 114 and the support beams 98, 100 and 104 for securing the switch assemblies rigidly to the three support beams.
- Unit 120 is similar to unit 82 however it has a cast frame structure 122 that is formed of two identical cast components 122A and 122B.
- the structure 122 includes two sleeve sections 124A and 124B.
- the intermediate support beam 100 is bifurcated having support beam segments 126A and 126B.
- the bifurcated support elements 126A and 126B have facing surfaces 127 with an insulator layer 128 mounted therebetween. Insulator layer 128 provides additional insulative properties.
- the cast frame structure 122 has the advantage of being formed of smaller and less complicated castings 122A and 122B.
